GSP hasn’t fought since November, when he worked his way to a split decision over Johny Hendricks at UFC 167. After the bout the fighter announced he was vacating the title due to personal reasons. The star has also relayed since that concerns over performance enhancing drugs in MMA, and a lack of random testing, contributed to his decision.

In 2011, the 32 year-old fighter tore his ACL and was sidelined for over a year as a result.
